This is a soba soup that's great not only for soba, but for many other things as well. The kombu, chicken, and mushrooms make this a super yummy soup.
I wanted to make a hot and delicious chicken and kombu dashi-based soba soup that's overflowing with vegetables.
If you add the koya dofu before seasoning, it will crumble, so first adjust the flavor and then add the koya dofu. Be sure to remove the scum.
